通过对四川凉山地区17个县市520个乡镇的1560个不同生态点野生荞麦资源的系统考察,明确了分布于该地区不同生态点的野生荞麦资源有7个和2个变种,同时也了解了该地区野生荞麦的原生境和三大主要分布中心,即海拔高度在1000m左右,温度较高的东部和南部金沙江沿岸分布中心,海拔高度在2000m左右,较低温度的中部分布中心和海拔高度在2500m左右,温度较低的西部分布中心。

Study on Primitive Environment and Main Distribution Centers of wild Buckwheat Resources in Liangshan of Sichuan

After systematically investigating the wild buckwheat resources of the 1560 different ecological areas in the 520 villages and towns of 17 counties in Liangshan of Sichuan, the author knows clearly that there are seven species and two varieties distributing this area.At the same time, the author knows the primitive environment and three main distribution centers, that is, the higher temperature east of an altitude of about 1,000m and the south of Jinsha River, the lower temperature central distribution center of an altitude of about 2,000m, the lower temperature west of an altitude of about 2,500m.
